APPARATUS FOR SCRAPING ORE FROM WINGS OF VESSELS.

SPECIFICATION forming part of Letters Patent N 0. 757,858, dated April 19, 1904. On'ginal application filed August 24, 19(13, Serial No. 170,523. Divided and this application filed January 9, 1904. Serial To all whom it may concern.-

Be it known that I, MATTHEW ANDREWs, a citizen of the United States, residing at'Oleveland, in the county of (luyahoga and State of Ohio, have invented a certain new and useful Improvement in Apparatus for Scraping Ore from Wings of Vessels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

Vessels for carrying bulk freightas, for example, iron ore-are usually constructed with a considerable distance from hatchway to hatchway. There must thus be much scraping of the load from between the hatchways and the wings of the vessel to get it beneath the hatchway in position to be unloaded. This is especially true where modern automatic unloading machinery is employed for raising the load. It has been proposed to scrape the ore beneath the hatchway by means of cables run from the dock; but this is not satisfactory, as the vessel during its unloading rises and shifts its position with reference to the cable-driving mechanism. Moreover, there is annoyance in the guiding of the cables over the hatchway, and they are in the way and liable to be tangled. I have found that the desired result can be very satisfactorily accomplished by placing across the hatchway a winding mechanism which rests upon the hatch-coaming and is anchored to it,

- cables running from this mechanism down into the hold and around suitable pulleys therein and scrapers being secured at the lower ends of the cables. By mounting the winding mechanism in a frame which spans the hatchway and placing it at one end of the hatchway the cables run directly from it to the hold, while the winding mechanism is out of the way of the elevating machinery. As soon as the vessel is unloaded the winding mechanism is removed and may be placed upon another vessel, and it is adapted to span hatches of difierent width to accommodate it to the different vessels.

My apparatus comprising, essentially, winding mechanism arranged and adapted to span the hatchway and scrapers operated by it, has been given a thorough test in actual practice,

(No model.)

unloading many ore-carrying vessels on the great lakes at the harbors of Cleveland, A'shtabula, Erie, Buffalo, and Detroit during the season of 1903 and has been found extremely efficient.

In the drawings, Figure l is a side elevation of a portion of a vessel broken away to show the hold. grammatic cross-section of the same. Fig. 3 is a plan, and Fig. 4 is a side elevation, of the winding mechanism I prefer to employ.

This particular form of winding mechanism is shown, described, and claimed in my application, Serial No. 170,523, filed August 24, 1903, of which this is a division.

Referring to the parts by letters, A represents a vessel, and a the hatch-coaming around the hatch ways thereof. Spanning these hatchways near their ends and resting upon the hatch-coamings a is a frame B, on which is mounted the winding mechanism. This winding mechanism comprises a pair of drums b b,

an electric motor 5 gearing b and I) from the motor, and clutches b and t, interposed between such gearing and the drums, levers b and 6 being provided for governing such clutches. The frame B is anchored to the hatch-coaming by a pair of hooks B B,which take over the coaming.

Leading downward from the drums Z) and b are cables C C. These pass around pulleys, as indicated at 0, suitably carried by the stanchionsa of the vessel. At the ends of the cables are scrapers D. A suitable electric switch (not shown) governs the motor 5 to drive it in either direction, and the levers b and b connect in either drum, as desired.

It will be noticed that there is considerable distance between the depending members of the gearing b 6* and the hatch-coaming a, on which the frame B rests. This allows the mechanism to be mounted on a much narrower hatchway. The distance between the gears is small enough so that the mechanism can be mounted on almost any hatchway in use,while the total width of the frame B may be great enough to span any of the hatchways as at present constructed.

1. The combination, with the hull of a ves- Fig. 2 is a somewhat diasel having suitable hatchways, of a frame carrying a winding-drum, said frame being adapted to span the hatchway and rest upon the hatch-coaming, means for anchoring the frame, and scrapers within the hold of the vessel arranged to be operated by said winddrum.

2. The combination, with a vessel having suitable hatchways and having hatch-00amings surrounding the hatch-openings, of a frame adapted to rest upon the hatch-00aming, means for anchoring said frame to the hatch-coaming, and winding mechanism car. ried by such frame.

3. The combination, with a vessel having suitable hatchways and having hatch-00amings surrounding the hatch-opening, of a frame adapted to rest upon the hatch coaming, means for anchoring said frame to the hatchcoaming and winding mechanism carried by such frame, cables leading from said winding mechanism down into the hold, pulleys'around which said cables pass, and scrapers operated by said cables.

4. The combination with a vessel having a hatchway, a frame arranged to span such hatchway and rest upon the hatch-coaming, hooks carriedby said frame and adapted to engage the coaming at the end of the hatchway, and winding mechanism carried by said frame.

5. The comblnation with a vessel having a hatchway, a frame arranged to span such 'hatchway and rest upon the hatch-coaming,

hooks carried by said frame and adapted to engage the coaming at the end of the hatchway, winding mechanism mounted on said frame, cables leading from said winding mechanism down into the hold of the vessel, pulleys carried by the stanchions of the vessel around which said cables pass, and scrapers secured to said cables.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. MATTHEW ANDREWS.
